To meet the research and development demands for precise and reliable analysis of ligand-receptor interactions, we provide comprehensive Cellular Biosensors for Ligand-Receptor Interaction services. Employing a wide variety of cellular assay platforms, together with extremely sensitive detection systems, we facilitate reliable real-time measurements of binding and cellular responses. We provide optimized biosensor design and cell model selection, strict validation of assays, and numerous analytical tools (fluorescence resonance energy transfer (FRET), surface plasmon resonance (SPR), high-content imaging, label-free technologies etc.) for excellent sensitivity, specificity and biological relevance. This approach is broadly applicable in drug discovery, receptor pharmacology, signal transduction and drug development. Our extensive quality control procedures and vast experience in the technical knowledge assure each project of high reproducibility, stability and data consistency. Our core services include:
Design genes, construct expression systems, and produce chimeric receptors and ligands.
Establish reporter cells to detect ligand-receptor binding.
Co-culture cells to monitor signal activation in real time.
Ensure cell stability and accurate and reliable signals.
Analyze data, provide reports, and provide technical support.
In the case study using the developed cellular biosensor to evaluate PD-1/PD-L1 immune checkpoint blockade, flow cytometry was used to assess the dose-response relationship between blocking antibody activation of the PD-1/PD-L1 interaction. The percentage of PD-1/PD-L1 interaction activation decreased significantly with increasing blocking antibody concentration, indicating that the antibody inhibited the interaction in a concentration-dependent manner. Data points represent the mean, and error bars represent the standard error. The horizontal axis is a logarithmic scale of antibody concentration.
We use cell lines stably expressing chimeric receptors, combined with rigorous control experiments, to ensure specific and reliable signals and avoid false positives.
Of course! Our platform supports high-throughput screening, enabling rapid and accurate identification of effective ligands or inhibitors, significantly reducing R&D time.
Yes, our sensor design is highly sensitive, enabling us to capture low-affinity but biologically important interactions.
Yes! We first expose the blocking agent to the stimulated cells and then observe changes in signal intensity, allowing us to accurately measure blocking ability.
Of course. We have an experienced team that can design and build custom sensors tailored to your specific receptor or ligand needs.
